David Cameron has sent a message to "petty" council bureaucrats ordering them not to strangle royal wedding street party celebrations with unnecessary red tape.

The Prime Minister also urged locals planning get-togethers on April 29 to "ignore" local authorities who try to "interfere" with their plans by bogging them down with paperwork and health and safety legislation.

Writing in The Sun on Monday, Mr Cameron said: "To those councils that are asking small groups of neighbours for licences, insurance and other bureaucracy the message is clear: Don't interfere, don't get in the way and don't make problems where there are none. Let people get on and have fun.

"There have been stories about petty bureaucracy getting in the way of party planners. But people who want to come together to celebrate with their neighbours should go ahead."

Mr Cameron will on Monday travel to the north of England with wife Samantha in a bid to get the nation into the party spirit and promote street celebrations.

The Department for Communities and Local Government is also expected to issue urgent new guidance for councils who have attempted to stop royal wedding festivities with unnecessary conditions.

In February, Transport Secretary Philip Hammond wrote to all local councils in England informing them that he was cutting Whitehall red tape by scrapping existing Government road-closure guidance. He said the move was designed to make it easier for councils to let street parties go ahead and allow local communities to celebrate without being inundated by paperwork.

It is estimated that more than 4,000 street parties have already been planned to mark Prince William's marriage to Kate Middleton.

Describing the historic event as "a special day for everyone in Britain", Mr Cameron urged the public to "bring out the bunting" and organise more parties.

"It's a chance for all of us to come together and celebrate the great things about our country," he added.
